Graphene-Reinforced CAD/CAM Restorations for MIH-Affected Molars in Adolescents: A Prospective Clinical Study

This study evaluates the clinical performance, marginal integrity, surface wear, color stability, and postoperative sensitivity of graphene-reinforced CAD/CAM indirect restorations (inlays, onlays, overlays) in molars affected by moderate to severe Molar-Incisor Hypomineralization (MIH) in adolescents. A total of 30 patients aged 10-16 years will receive minimally invasive indirect restorations fabricated from a nano-reinforced graphene polymer (G-CAM®). Clinical outcomes will be assessed using FDI criteria, VAS sensitivity scores, patient satisfaction, and digital 3D scans over a 12-month follow-up. The study aims to determine clinical acceptability and safety compared with historical outcomes reported for composite and lithium-disilicate indirect restorations.

Efficacy of Solventum™ Vitrebond™ Pulp Protect Liner/Base Used as a Liner/Base Under Dental Restorations

This is a clinical study evaluating a new dental product called Solventum™ Vitrebond™ Pulp Protect Liner/Base. This new product is designed to be used as a liner or base between the tooth and the dental filling, as well as for a procedure called direct pulp capping (DPC) if there is exposed pulp. Dental pulp is the part of the tooth that contains the nerves, blood vessels, and cells that keep your tooth healthy. This study will focus specifically on the liner/base application. In this study, the Solventum study product will be compared to a similar, commercially available product made by Solventum called 3M™ Vitrebond™ Plus Light Cure Glass Ionomer Liner/Base (Vitrebond Plus for short). The study will include participants who are at least 7 years old who have at least one tooth with moderate or advanced caries (tooth decay). The entire duration of the study is anticipated to be 2 years from when the first subject begins the study until the last subject completes the study. The duration of each study subject's participation will be up to 1 year consisting of an initial tooth restoration visit at baseline, a subject self-reported post-operative sensitivity assessment at 1 week reported by phone call, and in-person follow-up assessments at 1 month, 6 months, and 1 year post-restoration to confirm safety and effectiveness. The study will be partially blinded, which means that the participant and the dentist doing the assessments won't know which liner/base product is used on their tooth.

The Effect of Bleaching Application Mode on Bleaching-induced Tooth Sensitivity.

The aim of this study is to evaluate the effect of single versus multiple application protocols for in-office dental bleaching using two different bleaching gels (Pola Office Plus, SDI, 37.5% HP and Opalescence Boost, Ultradent, 40% HP) on the risk and intensity of tooth sensitivity, as well as the effect of the application protocol on the bleaching efficacy. Null hypothesis: There is no difference in intensity and risk of tooth sensitivity between single and multiple application of each gel and the application protocol dose not present significant effect on the bleaching efficacy.

Evaluation of In-office Bleaching-induced Sensitivity With 2 or 7 Days Interval Between Sessions

Clinical randomized single-blind trial, used to measure the level of tooth sensitivity (TS) after in-office dental bleaching sessions, on volunteers using a modified visual analog scale (VAS). The investigators selected for this study, 47 participants with color 2M2 or darker (Using 0M1 - 5M3 Vita bleaching shade guide). The investigators performed two bleaching sessions with an acidic 35% hydrogen peroxide gel with either a 1-week or 2-day interval. The investigators recorded the TS up to 48 h with a VAS scale and the color at baseline and 30 days after bleaching with a value-oriented shade guide and a spectrophotometer. The risk and intensity of TS and the color change were compared between the two groups.

Using Calcium Hydroxylapatite To Treat Gum Recession and Tooth Hypersensitivity

Study Purpose and Objectives: This study will utilize calcium hydroxylapatite (CaHA) to treat recession and hypersensitivity of the gums. The objectives of the study are: 1. to study the quality and quantity of changes in attached gums resulting from Radiesse(+) injections in the gingival tissue; 2. to determine the efficacy of Radiesse(+) in the reduction of tooth hypersensitivy caused by exposed roots relating to gingival recession; 3. to determine the efficacy of Radiesse(+) in the treatment of mild and moderate gingival recession.
